From 49f544b57243bf3fafbeabfcab5bdd1294d9d8f3 Mon Sep 17 00:00:00 2001
From: Bruce Evans <bde@FreeBSD.org>
Date: Sat, 21 Oct 1995 08:51:01 +0000
Subject: [PATCH] Return early in printreg() when the pointer is NULL.  For
 FreeBSD, the strings describing the drive status and error bits are so
 deficient that the pointer is always NULL.
